Andre Brown is now # 19; Tevin Broussard is now # 23; Jens Jeters is now # 42; Brian Price is now # 91; Skylar Nelson is now #99.

This includes the new walk-ons:

Jace Edwards is now # 10; Spencer Phillips is now # 26; Fred Blow is now # 29.

Because of this and/or other reasons probably, other players had a new jersey numbers reassigned to them as well; it's mostly the walk-ons but some of the scholarship players are affected by these jersey number changes as well:

I suspect that the PDF version of the roster is a bit more updated than the html version of it. For example, the PDF version has Simmons listed as a wide receiver now (he tweeted about this position change a few months ago sometime after the 2012 season ended). Also, the PDF version doesn't have # 89 Austin Rushing nor # 49 Karimu Osman seemingly indicating that they are no longer on the team.

There could be a couple of other changes on the roster such as on weight measurement or on position changes, but aside from what I saw on Simmons, I wasn't looking at those details in particular (y'all are more than welcome to however).
